Patent DE-2844998-A1 (DE)
Title: Concrete formwork scaffolding type roller guideway - has appliance metering roller pressure and positional change movement
Inventor: TOST HANS
IPC: E04G11/20
Filed: 1978-10-16
Abstract: A roller mounted in a sliding carriage is pressed against guiding tracks to effect parallel displacement of the hoist unit or scaffolding framework, in the roller guiding system for formwork units for concrete structures or similar. Use is made of devices for measuring the pressure being exerted, and for measuring any extent of displacement that occurs in the course of change in the unit position. An elastic intermediate member between sliding carriage and pressure spindle may be used for measuring pressure, with a metering rod (M) connected to its spindle abutment. This enables forces to be directly measured, so as to avoid excessive stressing.

Title: Plastic powder grain structure determn. - by heating suspension in fluid causing swelling and measuring ultrasonic attenuation
Inventor: MEYER KLAUS-RUDOLF DIPL ING DR
IPC: G01N29/032
Filed: 1979-03-14
Abstract: The grain structure of plastic powder is investigated by suspending it in a fluid which can cause it to swell, pref. at normal pressure below the temp. where swelling starts. After stirring the suspension is heated at a constant rate of rise of the temp. to produce a significant swelling. During the heating period the suspension or a part of it is exposed to the sonic vibrations of an ultrasonic generator with a frequency between 0.02 and 20 MHz. The attenuation of the sound waves is measured continuously and represents a direct measure for the grain structure of the plastic powder.
Patent DE-2914613-A1 (DE)
Inventor: ZWICKY RUDOLF DR
IPC: H02P27/05
Filed: 1979-04-11
Abstract: A drive having a double-supplied rotating-field machine (DM) makes it possible, by means of a variable-frequency, machine-commutated converter as the three-phase power source (DQR) for one of the two machine windings (WRO), for the rotation speed to be regulated from rest up to the maximum rotation speed with comparatively little complexity. In order to ensure an adequate commutation voltage, the operation is carried out in a known manner with the stator field and rotor field rotating in the same direction and the rotating-field frequency (fRO) increasing from equality with the other rotating-field frequency (fST) at rest to the maximum rotation speed. Feedback to the mains via a converter cascade in this case allows good efficiency, with a considerable portion of the power actually circulating via the converter, and with stringent frequency requirements on the machine-side converter at high rotation speeds. In order to solve the problem, while maintaining the essential advantages of a machine-commutated converter, the circuit arrangement makes it possible to break the overall rotation speed down into a lower range with rotating fields in the same direction and an upper region with rotating fields in opposite directions, the transition being achieved by changing the rotation direction of one of the two rotating fields by means of a rotation-direction reversing device (DUR) while keeping the direction of shaft rotation the same. In the case of the transition into the upper range, the variable frequency is reduced so that the maximum value remains low. <IMAGE>

IPC: G01N21/37
Filed: 1979-12-06
Abstract: The system has a sensor providing an electrical output subjected to a periodic variation in dependence on the amplitude of the measured value. The sensor output is used to control the frequency of an oscillator and the resulting FM signal is evaluated to display the measured value.
